Sudden Mortality in Captive White-Tailed Deer With Atypical Infestation of Winter Tick

open access: yesJournal of Medical Entomology, 2021
Abstract In October 2020, three captive male white-tailed deer, Odocoileus virginianus [Zimmermann] (artiodactyla: Cervidae), were found dead in central Pennsylvania and a fourth was euthanized due to extreme lethargy. The deer presented with high burdens of Dermacentor albipictus (Packard) (Ixoda: Ixodidae) (winter tick).

Linking weather conditions and winter tick abundance in moose

open access: yesJournal of Wildlife Management
AbstractClimate change may modify species distribution to higher latitudes, resulting in potential changes of parasite diversity and transmission dynamics in areas where animals might not be locally adapted to these new parasite species. In addition, climate change may increase the frequency and severity of infestations of parasites that are already ...

In the Southwest it infests livestock principally in the winter months. Around Kerrville, Texas, infestation may be found from late November through February.

Cytogenetics of Ticks (Acari: Ixodoidea). 10. Chromosomes of the Winter Tick, Dermacentor albipictus (Ixodidae)

The Journal of Parasitology, 1972
Karyotype, sex determination, and meiosis were studied in the one-host tick, Dermacentor albipictus. Males possess 20 autosomes plus 1 sex chromosome. Ten autosomal bivalents and 1 sex univalent are present at diplonemma, diakinesis, and metaphase I; reduction division, at least for the sex chromosome, occurs at anaphase I.
